Title: Adhesive for base of bulb
Inventor: TAMURA NOBUHIRO
IPC: H01J5/50
Filed: 1990-02-22
Abstract: PURPOSE:To improve the adhesive strength of an adhesive for silicon resin base by using silicon resin for the adhesive component, and specifying, concerning the average diameter, the minimum blending factor of an inorganic filler. CONSTITUTION:The blending factor y(weight%) of the inorganic fillers 31 to be blended in silicon resin 3 is specified as y>=138.443/(x+0.347)+64.100, to the average grain diameter x(mu) of the fillers 31. If the fillers large in grain diameters are blended to meet this relation, fellow grains of the fillers 31 intertwine with each other, whereby the adhesive force is reinforced, and even if it is approximately the same heating time as the case where a phenol adhesive is used, the shortage of the strength by the insufficiency of hardening of the silicon resin itself is supplemented. Accordingly, even if it is used for a phenol resin base adhesive charger or a base bonder as it is, enough strength can be gotten.
